Making good even better: as the technology leader in elemental analysis, we benefit from more than 120 years of experience. Now we used our technical know-how to take our proven micro elemental analyzer vario MICRO cube to the next level - always focusing on the users' needs.
The result is the new UNICUBE for the elemental analysis of carbon, hydrogen, nitrogen, and sulfur. UNICUBE combines the low costs and the sensitivity of a micro elemental analyzer with the flexibility and outstanding robustness of a macro analyzer.
0.1 mg pharmaceuticals can be analyzed just as precise as up to 1 g inhomogenous soil samples. Volatile gasoline or temperature-proof silicon carbide can be analyzed just like coal, foodstuff or sewage sludge - without restriction of the elements, simultaneously for CHNS or for the combinations CNS, CHN, CN, O and Cl in one sample run.
UNICUBE utilizes Elementar's proprietary and improved direct Temperature Programmed Desorption (direct TPD) technology for highest reliability and performance in gas separation. In combination with the most powerful detector in the market, the instrument is capable of determining samples with C:N and C:S elemental ratios of up to 12,000:1.
Clearly arranged, easily accessible system components as well as a furnace that slides out minimize maintenance and maximize uptime. The tool-free clamp connection system ensures a reliably leak-tight instrument at any time. Thus, users can enjoy smooth analyses and confidence in their results.

CHNS, CHN, CNS, CN: all available from the basic unit.
Optional detection of oxygen and chlorine (with TCD or IR)
All modes are suitable for the analysis of solid & liquid organic and the majority of inorganic samples.
High temperature combustion
quantitative sample digestion at up to 1200 °C – with ten years furnace warranty (1800 °C at the point of combustion when tin foil is used). This is the prerequisite for 100% recovery also with samples difficult to combust. Jet injection of oxygen directly to the sample leads to highest oxygen concentrations at the point of combustion and low gas consumption
Largest weighing range
from micro (< 0.1 mg) to macro (1 g soil) sample weight, depending on requirements up to 50 mg organic matter
Largest dynamic range of element concentrations and element ratio
up to 14 mg C abs. (50 mg C in CN mode, requires optional configuration) or 10 mg N abs. (or 100%, depending on analysis mode and sample matrix), from ppm to 100%
Direct Temperature programmed Desorption (direct TPD)
Separation of gaseous components with an optimized TPD column for perfect separation without peak overlap. Automated optimization of the time per analysis
Multipoint calibration
stable over months and matrix-independent
Instrument control
with a standard PC for perfect results also for unknown or heavily variable sample matrices with integrated sample feeder for 120 samples, 21 CFR part 11 functionality available. Possibility for remote service due to full digitalization of the instrument electronics. System control under Linux also possible.
One high-performance instrument for all applications
No expensive special catalysts, easy ash removal from the combustion tube and long lifetime of all components are the basis for a low cost of ownership
Clean, safe, fast
The analysis only takes a few minutes, no aggressive or toxic chemicals are used, Helium carrier gas (Argon possible alternatively)
Easy installation requirements
48 x 55 cm benchtop space, 1 power supply (230, 110, 100 V), and two gases are sufficient for maintenance free long time operation

vario Liquid Sampler, VLS:
The VLS automated sample feeder is used for liquid injections directly into the combustion chamber.
Manual gas/liquid injection:
for the injection of liquid or gaseous samples via a septum free injector port and a micro-syringe.
Sample former with pressing tool:
for the compaction of the wrapped samples and removal of air in soil samples.
Manual pressing tool:
for the manual compaction of the wrapped sample.
We offer all consumables required for the operation of our analyzers. These include combustion/reduction tubes, chemicals, measuring standards, sampe containers, seals, and instrument-specific wear parts. We do not compromise on quality of our parts and chemicals – this is the prerequisite of a guaranteed long lifetime of our instruments. When using original consumables from Elementar, a 10 year warranty on high temperature combustion furncace and thermoconductivity cell (TCD) is granted.
